2. The Best Multimeters to Safely Test Your Electrical Systems - AOL

   www.aol.com/best-multimeters-safely-test...

   Capable of measuring AC/DC voltage up to 600 volts and 10 amperes of DC current, as well as functioning as an audible continuity tester, this machine is versatile enough to cover the majority of ...

3. Current clamp - Wikipedia

   en.wikipedia.org/wiki/Current_clamp

   This allows measurement of the current in a conductor without the need to make physical contact with it, or to disconnect it for insertion through the probe. Current clamps are typically used to read the magnitude of alternating current (AC) and, with additional instrumentation, the phase and waveform can also be measured. Some clamp meters can ...

4. Four-terminal sensing - Wikipedia

   en.wikipedia.org/wiki/Four-terminal_sensing

   Four-point measurement of resistance between voltage sense connections 2 and 3. Current is supplied via force connections 1 and 4. In electrical engineering, four-terminal sensing (4T sensing), 4-wire sensing, or 4-point probes method is an electrical impedance measuring technique that uses separate pairs of current-carrying and voltage-sensing electrodes to make more accurate measurements ...

   Ammeter, e.g. Galvanometer or Milliammeter (Measures current) Multimeter e.g., VOM (Volt-Ohm-Milliammeter) or DMM (Digital Multimeter) (Measures all of the above) LCR meter - inductance (L), capacitance (C) and resistance (R) meter (measure LCR values) The following are used for stimulus of the circuit under test: Power supplies; Signal generator

6. Multimeter - Wikipedia

   en.wikipedia.org/wiki/Multimeter

   To measure alternating current, which changes up and down repeatedly, a rectifier is inserted in the circuit so that each negative half cycle is inverted; the result is a varying and nonzero DC voltage whose maximum value will be half the AC peak to peak voltage, assuming a symmetrical waveform.

   Measures current Capacitance meter: Measures the capacitance component Current clamp: Measures current without physical connection Curve tracer: Applies swept signals to a device and allows display of the response Cos Phi Meter: Measures the power factor Distortionmeter: Measures the distortion added to a circuit Electricity meter

8. Source measure unit - Wikipedia

   en.wikipedia.org/wiki/Source_measure_unit

   The source measure unit (SMU), or source-measurement unit, is an electronic instrument that is capable of both sourcing and measuring at the same time. It can precisely force voltage or current and simultaneously measure precise voltage and/or current. An SMU instrument can source and sink power in all four quadrants.
